Lostenen, Glacial erratic in Pedersöre, Finland

During the last ice age, massive glaciers plucked this rock from distant bedrock and transported it across the region. The boulder was deposited at its current location in Pedersöre as the ice melted and retreated.
Finnish geologists and researchers frequently examine this glacial erratic to understand the patterns of ancient ice movements and regional geological development.
The boulder is easily spotted in the Pedersöre landscape and is typically accessible to visitors year-round. Wear sturdy shoes to explore the ground around this geological landmark comfortably.
The stone at Lostenen originated from a different geological region and was carried hundreds of kilometers by glacial flow. Geologists can trace its source by studying the mineral composition and comparing it with bedrock elsewhere.
